Linear smoke detectors in fire protection

Abstract

Smoke detectors generally present the most frequently used fire detectors. These detectors have great appliance because smoke presents the consequence of many fires. These detectors can be realized as point smoke detectors and linear smoke detectors, while special smoke detectors are used for special purposes. Their efficiency is the biggest in the cases where fuel material produces smaller or larger amounts of smoke. The use of smoke detectors in the form of linear smoke detectors is particularly significant in rooms with huge dimensions and huge ceiling height. This paper was written to present work principle of linear smoke detectors and their installation in objects related to valid standards (EN 54, BS, NPB 88-2001, VDE 088-2 and NFPA 72).
